ROSS M. TAYLOR, OF ALLEGAN, MICHIGAN.

PIPE-BOWL AND IMPROVED PROCESS OF MAKING THE SAME.

Specification of Letters Patent.

Patented Feb. 15, 1921.

Application filed April 23, 1920. Serial No. 376,089.

To all whom it may concern:

Be it known thatl, Ross M. TAYLon, a citizen of the United States,residing at Allegan, in the county of Allegan and State of h lichigan,have invented certain new and useful Improvements in PipeBowls andImproved Processes of Making the Same, of which the following is aspecification.

This invention relates to improved pipe bowls and to the improvedprocess of making the same.

The main object of the invention is to provide a pipe bowl made of woodor similar material with a suitable absorbent lining that shall bedurable and effective in use. I

Objects relating to more details will definitely appear from thedescription to fol.- low.

I accomplish the objects of my invention by the devices and meansdescribed in the following specification. The invention is clearlydefined and pointed out in the claims.

A structure which is a preferred embodiment of my invention, with themeans for producing it, is clearly illustrated in the accompanyingdrawing, forming a part of this specification in which:

Figure I is a perspective of a pipe made according to my invention.

Fig. 11 is a detail sectional. view through the bowl of the pipe inplace on the work table of a drill press, taken on a line correspondingto line 22 of Figs. I and Ill.

Fig. 111 is a detail view of the spinning head or mandrel located in adrill press for carrying out the process of making my improved pipebowl.

Fig. IV is a detail view showing how the spinning head or mandrel isforced into the bowls to shape and conform the cement or plasticmaterial and finish the surface thereof.

In the drawing, similar numerals of reference refer to similar partsthroughout the several views, and the sectional. view is taken lookingin the direction of the little arrows at the ends of the section lines.

Considering the numbered parts of the draw ng, 1 is the wood shell of apipe bowl containing an annular groove 2 near the top thereof. 3 isplastic material which may be either Portland cement or plaster of331118 or a mixture of the two or other plastic mixture. This isintroduced into the bowl of the pipe comparatively wet and in aconsistency to be readily molded. The bowl is then placed under thechuck 6 of a drill press carrying a suitable mandrel, having a spinninghead 5, .i itably flanged at 5. lhe pipe bowl is supported in a suitableperforated plate aton the drill press table. The head is spun by thedrill press and forced into position and effectively compacts andconforms the plastic material to place, and by the rotation and rubbingperfects and finishes the inner surface thereof, so that when the samehas been set, a pipe is produced having a lining of porous material welladapted to absorb moisture from the tobacco and having a firm finishedinner surface.

llaving thus described my invention, what I claim as new and desire tosecure by Letters Patent, is A 1. In a pipe bowl the combination of awooden shell with an interior annular depression toward the top, alining of cement or similar plastic material suitably conformed to saidbowl and its inner annular depression and having a compacted dense innersurface, as specified.

2. The process of manufacturing a wooden pipe with plastic liningconsisting in introducing the lining material into said pipe in a moistbut semi-solid condition and conforming the same by a properly shapedspinning mandrel to compact the material. and finish the inner surfacethereof.
